Comment 1 for bug 1582669

I was finally able to get startup notification work in xfce4 panel and also in the Thunar file manager by applying the attached patch and without setting GDK_CORE_DEVICE_EVENTS to true in /var/lib/lightdm/.pam_environment (I simply deleted this file). With the patch, unity-greeter displays correctly the mouse cursor and works as expected.

I used the informations from Message #5 from this page: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742460

and since I don't know the vala language, I used in the patch an external call to a C function.

I don't know if this solution is ugly or not, but it seems to work well...
